IMPROVEMENT IN DISTRIBUTING APPARATUS FOR DERRICKS.

Specification forming part of Letters Patent No. 152,149, dated June 16,1874; application filed March 28, 1874.

To all whom it may concern:

Be it known that I, J OHN MINNIoH, of Lebanon, in the county of Lebanonand State of Pennsylvania, have invented a new and valuable Improvementin Distributing Apparatus for Derricks; and I do hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation of the same, reference being had to the annexed drawings,making a part of this specification, and to the letters and figures ofreference marked thereon.

Figure 1 of the drawings is a representation of a front view of myelevator. Fig. 2 is a detail View of the same, and Fig.3 is a sectionalview.

This invention has relation to derricks for elevating coal from vessels,and for other purposes; and it consists mainly in the construction of arack-bar having a pivoted guidingeye, and receiving through it the ropeof the elevator-bucket, as will be hereinafter more fully described.

In the drawings hereunto annexed, A designates a house, which isconstructed upon a suitable frame-work, B, on the upper end of which isa derrick-beam, B, that overhangs an opening through one end of thehouse for the admission of the elevator-bucket O. The elevating-rope apasses over pulleys applied to the derrick-bar, and is carried downthrough an eye, I), which is pivoted to the outer end of a rack-bar, D.This rope a has attached to it the elevating-bucket O. The rack-bar islongitudinally movable between guides, which are slightly inclined, andthe teeth of this rack-bar engage with the teeth of a pinionspur-wheel,- c, the shaft of which has its bearings in a beam, E, andcarries on one end a hand-crank, c. On top of the bar D is-a rib, f,with which a pivoted catch-arm, g, is intended to engage. This arm gcrosses the bar D, and is held down upon it by means of a weight, w.Beneath the catch-arm g is a tripping-lever, h, which is connected by apushrod, h to a treadle, h arranged on the floor of the house Aalongside of the crank-arm c, where it will be convenient toapersonhaving hold of this arm. H designates a hopper, which is constructedupon the floor of the house A at the front opening of this house, andfrom which radiate one or more spouts, H, for conducting off the coal orother sub stances in different directions. Each spout has a valve, 2',applied in it, by means of which the flow of grain from it can bestopped at pleasure.

When the bucket G is filled and elevated to the proper height, thecatch-arm g is raised and the bar D allowed to move back, carrying withit the bucket over the hopper H. The load is then discharged from thebucket into the hopper, after which the bar D is moved forward byturning the wheel 0, so as to carry the bucket outside of the house tobe lowered for another load. The bucket O is hung in such manner thatwhen it is fully raised, and the bar D is released from its catch 9, it(the bucket) will of itself swing over the hopper.

The eye-piece b is pivoted at b to the front end of the bar D andallowed to vibrate freely, so that it will accommodate itself to thedifferent positions of the rope to without crampin g this rope or undulywearing it. The move ments of the eye-piece b are limited by a transverse pin, D which passes through a curved slot in said piece, as shownin Fig. 3.

hat I claim as new, and desire to secure by Letters Patent, is-- Thepivoted guiding-eye I) on rack-bar D, arranged over a hopper, andreceiving through it the rope of the elevator-bucket O, substantially asand for the purposes described.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

JOHN MINNIOII.
